Megane 53 rear window stuck down?

My 53 Megane Scenic rear window is stuck down. It seemed to happen when I double locked the doors and it came downon its own. Hubby took it to our local (non Renault) garage and they took the panel off and reckon the motor has gone. £200 plus estimate repair. Hubby had tried to get door panel off but apparently you need specialist tools from Renault which cost a fortune. Has anyone got the door panel off?
PS Will also try the remove fuse/deadlock ideas on here to see if can get it up again.
